Xeldrin 10 mg Capsule is a proton pump inhibitor (PPI) manufactured by ACI Limited in Bangladesh. Each capsule contains 10 mg of Omeprazole in enteric-coated pellets, designed to suppress gastric acid secretion by inhibiting the H+/K+ ATPase enzyme system in the stomach lining. This mechanism effectively reduces both basal and stimulated acid production, providing relief from acid-related gastrointestinal conditions.
